Did you know Canada.. It was three Canadian doctors who developed Pablum.
Pablum is a soft, bland cereal for infants created in 1931 and originally marketed by the Mead Johnson Company. The cereal marked a breakthrough in nutritional science: it helped prevent rickets, a crippling childhood disease, by ensuring that children had sufficient vitamin D in their diet. A popular addition to the infant's diet and remains a top choice by parents for infant food today.
Along with the nutritional aspect Pablum is palatable to infants and easily digested without causing side effects like diarrhea or constipation. It is also unlikely to cause allergic reactions - a big concern for parents today.
It was three Canadian doctors: Frederick Tisdall (1893-1949), Theodore Drake (1891-1959), and Alan Brown (1887-1960) in collaboration with nutrition laboratory technician Ruth Herbert along with Mead Johnson chemist Harry H. Engel who developed Pablum at the Hospital for Sick Children in Toronto.
